Technical field
The invention belongs to holder for aerial photographing technical field is and in particular to a kind of holder for aerial photographing of omnidirectional shooting.
Background technology
Unmanned plane low-altitude remote sensing system is on the basis of realizing Imagery Map, special to photogrammetric stereoplotting
Field is developed.Oblique photograph technology is an international survey field new and high technology developed in recent years.It has been overturned in the past
The limitation that orthography can only shoot from vertical angles, by carrying multiple stage sensor on same flying platform, simultaneously from one
Individual vertical, five different angle acquisition images of four inclinations, user are introduced the world truly directly perceived meeting human eye vision.
Aviation tilt image can not only truly corresponsively principle condition, and can by advanced location technology, embedded accurately
Reason information, more rich image information, the Consumer's Experience of higher level, greatly extend the application of remote sensing image, make remote sensing
The sector application of image is more deep, tilts introduction and the application of image technology, also will make three-dimension tidal current high at present
Cost substantially reduces.
But independent photographic platform of the prior art is typically by being fixedly installed one downwards, four different directions
Different angles are carried out image collection, realize omnidirectional shooting by camera respectively, but this holder for aerial photographing exists, and volume is big, machinery knot
Structure is complicated, quality is big, the little and expensive shortcoming of compensation range.
Content of the invention
In order to solve, this holder for aerial photographing volume is big, mechanism structure is complicated, quality is big, the technical problem that inconvenience controls, this
Invention provide a kind of can flexible camera shooting angle, structure be simple, small volume, installs taking photo by plane of stable omnidirectional shooting
Head.

The operation principle of the holder for aerial photographing of omnidirectional shooting of the present invention is:
Unmanned plane transmits position signalling to controller, and controller, according to lamination rate set in advance, controls described rotation
Camera and first camera are shot, by controlling the rotation of described steering wheel, thus controlling the lens direction of described rotating camera,
The visual axis tilt of two rotating camera is downwards but contrary each other, and two rotating camera shoot rightabout scenery, with the first phase
Machine coordinates, to the scenery omnidirectional shooting under holder for aerial photographing.The anglec of rotation of two rotating camera, by location structure, every 90
Degree orientates a direction as, but is fixed with second camera so that the platform of its outer surface can not because camera upper shell is tilted
Extend fully into whole outer wall, if two rotating camera each other towards when be 0 degree, two rotating camera can be with left rotation and right rotation 90
Degree, it does not enable oppositely arranged each other, and the scenery in the opposite direction of every rotating camera passes through another rotating camera and shoots.
The present invention controls the contrary rotating camera of two shooting direction using a steering wheel simultaneously, decreases the number of steering wheel
Amount, mitigates the quality of holder for aerial photographing, and makes more compact structure, volume is less, thus reducing the resistance of flight.By outside
On housing setting vibration absorber, in camera case filling cushion blocking it is ensured that second camera stability it is ensured that shoot
Quality.Because holder for aerial photographing works out of doors, it is provided with sealing structure in the through hole of shell body and the position cooperating, protects
Card water proof and dust proof, but in order to radiate, it is provided with waterproof vent valve it is ensured that the normal operation of first camera, second camera.
